The purpose of this study is to present the status of non - verbal communication and to evaluate
consumer 's opinion about it. Non-verbal communication was classified into physical language, spatial
language, pseudo - language, and appearance language. Service quality was classified into tangibility,
reliability, reactivity, assurance, and empathy according to the purpose of visiting the optician. We surveyed
consumers who visited the optometrists in Seoul and analyzed the responses with the IBM SPSS Statistic 22 program. As a result, the body language and the phonetic language of the optician were evaluated
relatively low compared with the spatial language and the appearance language. In service quality,
confidence and responsiveness were rated low for most visits. The body language and physician language
of the optician showed a relatively positive correlation with service quality, customer satisfaction, and
repurchase intention. In this study, we conclude that Non-verbal communication has a significant effect on
service quality, customer satisfaction and repurchase intention. Therefore, education of physician 's body
language and physician language should be strengthened to improve customer satisfaction as well as
repurchase intention.
